Dr Motor, please stop invading every thread with these broken logic equations that claim these motors are all identical - YOU CAN NOT PROVE THIS BEYOND REASONABLE DOUBT. How do you know the copper windings are the same exact copper, wound with the same tension, the same pattern,? How do you know they all have the exact same bearings, with the exact same lubricant, with roller balls of the exact same material? How do you know these all went through the same quality checks? How do you know the strand counts are the same in the wires? How do you know the solder is the same chemical composition? I could go on, but I hope you get the point.

Everyone here gets your point that these motors may likely be made in the same place, and that companies like Hacker may possibly be charging more money for the exact same motor.

YOUR POINT IS UNDERSTOOD, YOUR LOGIC IS FLAWED, SO PLEASE STOP, IT IS FREAKING ANNOYING.

Why don't you just start your own thread about motors - when topics like this 4S practice plane come up, you can do your little research and add to your list, and you would be creating a resource for people who actually cared to know about this. It is not right to take over threads of different topics and turn them all into these illogical motor debates.
